High energy storage and delivery are observed for supercapacitor electrodes based on NiO/Ni nanocomposite materials. In their Communication on page 6847 ff., J. Q. Xiao and co‐workers report a simple, cost‐effective, and potentially scalable technique for fabricating support‐ and additive‐free supercapacitor electrodes. The maximum performance of energy storage and delivery were simultaneously achieved by developing a slow‐charging and fast‐discharging procedure.
